VALVE INSTALLATION.

Originalapplication filed January 24, 1928, Serial No. 249,043. Divided and this application filed June 26, 1928.

The present invention relates to valve installations and more particularly to slidably mounted valves adapted for movement to open or close a port defined by a valve seat.

in the present embodiment of the invention the valve is preferably formed of sheet metal. possessed of an inherent resiliency which is utilized in effecting a tight seal against the valve seat when the valve is in its closed position, the object of the invention being the provision of a valve of the class referred to, which will resiliently bear against the valve seat when in closed position, in combination with means for moving said valve to and from its seat.

Another object of the invention is the provision of actuating mechanisms for said valve, equipped with means for decreasing a dimension of the valve when it is pushed towards its seat, and for increasing said diinension after said valve has been forced to its seat, thereby facilitating the operation oi moving the valve, and insuring a tight joint between the latter and said seat.

The present invention is a division of my eo-pending application, Ser. No. 249,045, lavatory fixture, filed J an; 24:, 1928, and is here shown and described as applied to the fixture disclosed in said application, but it is to be understood that the invention is not limited to such specific usage.

Other objects oi? the invention will be made apparent in the following specification, when read in connection with the accompany ing drawings forming a part thereof.

In said drawings 1-- Fig. l a section taken vertically through the basin or bidetdescribed in my co-pending application referred to.

h ow referring specifically to the drawings, in which like reference numerals indicate like parts throughout the several views, 1 indicates any basin or fixture adapted to receive afluid, and equipped with an outlet drain pipe 2. The basin 1 is provided with an outlet port 3, preferably of rectangular confor- Serial No. 288,388.

ination, to prevent whirling action of water 111 passing therethrough, the lower portion of the basin surrounding the outlet, being downwardly extended to form a squared chute 4., of the same inside dimensions as the port 3.

Surrounding the chute 4: is a valve seat, 5, preferably formed of relatively soft rubber. The seat 5 extends upwardly over the outside of the chute 4., and tightly secured thereto, as will be hereinafter explained, the lower portion of the seat being positioned substantially below and in the vertic: l. plane oi the walls of the chute, and equipped with enlarged rubber heads 6, adapted for contact by the valve closure element, the top portions of said seat being adapted to fit against the lower surface of the bottoni of the basin 1. The top portions of the heads 6 are flattened or shouldered, to support a screen 6.

The valve housing comprises an elongated hollow casting 7, having an inlet in its top near its rear end, said inlet being defined by integral upstanding flanges 8, adapted to e tend upwardly over the side walls or the seat 5, and horizontally extending flanges l parallel to the bottom of the basin l. in actual practice I prefer to place the valve seat on the casting 7, before the latter secured to the basin 1, and, in this process, the seat 5, having been molded to the proper size, is inserted into the inlet port of the casting 7, so that the lower edges of the heads 6 will project downwardly into the interior or the casting to point just slightly below the lower surface of the top wall of the latter. In this position the sides and top of the seat may be adhesively or otherwise secured to the flanges 8 and 9 of the casting 7, it de sired, and the screen 6 is laid upon the shoulders carried on the upper portion 01 the heads 6. The casting 7 is then placed in position as shown in Fig. 2, the lions; S) bci bolted or screwed to the bottom 0 the basin 1., and firmly retaining the casting and seat in proper assembled condition with respect to the port 3, the seat and lS vertical walls, and its horizontal flanges, operating as paclc ing gaskets preventing leakage.

Reciprocably mounted within the casting 7, is the valve element 10, as best illustrated in Fig. 2. It comprises two leaves 11 and 12 of spring nietal integrally connected at the one end, and normally tending to assume the distended position shown in Fig. 8. The

ill)

Q leaf'ilprovided' at its front end, on each side, with integral, rearwardly and downwardly extending curved guide fingers 13, and the leaf 12 is also equipped with similarly shaped but upwardlyextending"guide fingers 14. Inaddition thereto all of the fingers are provided with hooks on their rear edges,

as shownfin Figs. 2 and 3. Near the rear end'o'f tli'e" floor'jof the casing 7 is an integrally formed elevated boss 7', adapted to cause fiexure of the body, of the lower leaf {12,jalnd cause the valve 10 to snap into and out of operative position, under the power of actuating mechanism to be described.

Mounted for slidingvmovementin an apercare formed in the front endbftlie casting/Z,

is a bar 16, here shown as round in cross-section,v The bar extends into theval ve'casing throu h suitable'packing, the flattened front end 1 "thereof being entered between the free ends 18 and"19 o-f' th.leaves 1'1 and 12, re-

spectively. Adjacent its inner end the bar 16 carriestwo circular pins and 21, project y ingfrorn each side of the'bar to a-po'int adja- 7 desired, or provided with anti-friction devices. I V

v -Thecvallve element-10 is here shown as actuated by a bell crank lever control 22, the

inner end of said lever being pivoted at 22 to'a' connecting. rod 23', the latter beingpivoted in a bracket 24secured to the basin 1, the rod 23 terminating in a loop 25 operatively secured to the end of the bar 16-. As il lustrated in Fig. lthe valve'ltl is'in its closed positiom thelever 22 having been raised. In this position, when'itis desired to open the valve, the lever 22 wil'l'bedepressed, thereby causing the loop 25 to -move away from the casting,- and exert a pullupon' the outer end of the bar 16. Such pull will ca'usethe pins 20 to ride along the inclines 15 15 provided on-the oppositely disposed edges of the ends of the hooks 15,- 15,-andto enter the sockets formed by'said hooks, assuming the dotted line osition shown in Fi s. 2 and 4. in which position. a continued pull on 'the rod 16 will cause said -pins20 to bear against the oppo sitely curved inner edges of the fingers'13 and 14, and force the, leavesll and 12 together, thereby reducingthe distance between the V leaves, decreasingthe'prossure ofv the leafll upon; the seat 6', and facilitating the operation of drawing the valve from its seat. Continued pull on the bar 16 will cause the lower surface of'the leaf 12 to-rideo-ver the boss 7,

e 5 vthereby relieving the I 6 pressure of the upper surface of the leaf 11' on. the heads 6, and per-- mitting easy movement of the valve to the front of the casting to allow the flow of water through the port 3. The fingers 14 are provided with ledges 22, adapted to receive the pin 21 and support the bar 16 in proper position.

To restore the valve to its closed position the lever 22 is raised, causing the pins 20 to bear against the front edges of the hooks 15, 15, and thereby forcing the leaves 11 and 12 together and relieving the friction on the leaves as they travel rearwardly in the castmg. In the rearward movement of the valve '10 the rear end thereof is forced over the boss 7', and the valve will snap into position, the boss 7 T causing the leaf 11 to be pressed tight- 1 1 against the heads 6. In its closed position the rear end of the valve 10 is located ad'acent the curved rear end of the casting 7. In this position the pins 21 are pressed forcibly against the front edges of the. curved fingers 13 and 14, and tend to push apart the free ends of the leaves 11 and 12, the lever 22 preferably being connected to a spring 23', and being adapted to hold the pins 21 against said front edges of the fingers, the pins operating as a wedge to hold the spaced ends of the leaves apart. The pins 20, at this time. have been forced between the hooks 1,5, and are in the position shown in Figs. 2 and 4.

An over-flow pipe 27 leads from the basin 1 to the interior of the casting 7, and, in order to take off the over-flow therefrom, a lurality of grooves 28 are formed in the oor of the casting, and lead to the drain 2, as will be understood.

From the foregoing it will be noted that, while the leaves 11 and 12 are always exerting their resiliency to hold the leaf 11 against the heads 6, the actuating mechanism here disclosed is well adapted to first decrease the pressure of the leaf 11 upon the seat, and then move the valve to open position, and to later reduce the distance'between the leaves and restore the valve to its seat. In actual manufacture the components are so designed that the raised boss 7 will cause the valve, in its movements, to snap into and out of its closed position as the rear end thereof rides over said boss.

lVhenever it becomes necessary to renew the valve seat, or to make any repairs, the bolts 29 and 30 are removed, a door 31 being provided in the foundation of the basin here shown, to permit access of the operator.
